We're actually at about 90 days with these guys and they've developed their secondary sex characteristics and are ready to start spawning themselves.
There are at least a dozen in the oldest cohort, but it is difficult to count.
They're fast and difficult to photograph.
I tried to add these as photos, but had to add them as files. For whatever reason, the photos always seem to make it to 99% but then stop there. I walked away for 30 minutes and came back and they still hadn't finished.
Wow, that's very cool. Congratulations, Becca!
